Description

A kind of trailer closing component structure expanding carriage box volume capacity

Technical field

This utility model relates to a kind of boxcar closing component structure, is specifically related to a kind of trailer lock expanding carriage box volume capacity Close structure.

Background technology

Freight Transport is one of major way of modern transportation, is also two the basic transporter constituting the transport of land goods One of formula, it occupies an important position in whole transport field, and plays the most important effect.Cargo carriage board at present On lockset be divided into external and built-in two kinds, the lock of external lockset is arranged on the outside of platform floor, and car door arranges locking bar And latch hook, latch hook hooks lock and locks.External lock is easy for installation, but the space in compartment can reduce.When outside compartment When portion's width dimensions is 2540 millimeters, interior width is only 2344 millimeters, and interior space is relatively small.The knot of built-in lockset Structure is as it is shown in figure 1, lock 1 is arranged on the inner side of side bar 2, and locking bar 3 is arranged on car door 4, and the lower end of locking bar 3 is provided with latch hook, Latch hook hooks lock and locks.The lock structure so arranged, lockset weight is big, when full car all uses this lockset, car load weight Amount can increase by 17 kilograms.

Utility model content

This utility model is for solving above-mentioned the problems of the prior art, it is provided that a kind of trailer lock expanding carriage box volume capacity Close structure.

This utility model is adopted the technical scheme that by the above-mentioned technical problem of solution:

A kind of trailer closing component structure expanding carriage box volume capacity, including lockset and be positioned at car door and the conjunction of junction, compartment Page, described lockset includes the lock being arranged on inside side bar and is arranged on latch hook and the lock handle of locking bar lower end；Described locking bar Being arranged on car door, latch hook is rotatably installed on locking bar up/down perforation；Described hinge is non-centrosymmetrical butterfly Hinge, including left side hinge, right side hinge and the mandrel of centre.

Being provided with the lock fixture bent inwards inside described side bar, lock is arranged on the upside of lock fixture.

The upper outside of described side bar is provided with the seal angle bent inwards.

Outside the left side hinge of described butterfly hinge to outside length and the left side hinge at mandrel center to right side hinge The length ratio in outside is between 3:5 to 2:3.

Described right side hinge is that upper and lower is outwardly, and the wing shape that middle part inwardly concaves, in the hinge of left side Between be formed one with right side hinge shape and breach of the same size.

Advantage of the present utility model and having the beneficial effects that:

Trailer closing component structure of the present utility model, employing is arranged on the concealed type lockset inside side bar and ties mutually with butterfly hinge Close, it is possible in the case of not increasing container external volume, be effectively increased the volume of container；Effectively save space, will not take Size in case and outside case.And this concealed type lockset is more lightweight than original lockset, intensity is high.Butterfly folding is lightweight, contact surface Greatly, car door connects together the effect with firm reinforcement with compartment.Normal car door opening angle 90 degree, of the present utility model Butterfly folding can open 180 degree, saves space and is easy to handling goods.

Detailed description of the invention

For making those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with the accompanying drawings to this reality It is further elaborated with novel.

The trailer closing component structure expanding carriage box volume capacity of the present utility model, including lockset be positioned at car door and compartment and connect The hinge at place.Fig. 2 is the sectional side view of lockset of the present utility model；Fig. 3 is the top view of lockset of the present utility model.Such as Fig. 2 and Shown in Fig. 3, this lockset includes the lock 5 being arranged on inside side bar 2 and is arranged on latch hook 7 and the lock handle of locking bar 3 lower end.Described Being arranged on car door 4, latch hook 7 is rotatably installed on locking bar 3 locking bar 3 up/down perforation.

Being provided with the lock fixture 6 bent inwards inside side bar 2, lock 5 is arranged on the upside of lock fixture 6.Side bar 2 Upper outside be provided with the seal angle 7 bent inwards, prevent rainwater between side bar and locking bar space penetrate into.During use, Moving lock handle makes latch hook rotate, and hooks the lock being fixed on side bar, completes locking.

Fig. 4 is the structural representation of butterfly hinge of the present utility model.As shown in Figure 4, the hinge that this utility model uses For non-centrosymmetrical butterfly hinge 11, including left side hinge 10, right side hinge 9 and the mandrel 12 of centre.Right side hinge 9 is presented Portion and bottom are outwardly, the wing shape that middle part inwardly concaves, the intermediate formation of left side hinge 10 have one with right side hinge shape With breach of the same size.During Guan Bi, right side hinge 9 is just fitted in the breach of left side hinge 10.This hinge can open 180 Degree, saves space and is easy to handling goods.

Outside the left side hinge of butterfly hinge 11 to outside length d1 and the left side hinge at mandrel center to outside the hinge of right side The ratio of length d2 of side is between 3:5 to 2:3.

Trailer closing component structure of the present utility model, employing is arranged on the concealed type lockset inside side bar and ties mutually with butterfly hinge Close, it is possible in the case of not increasing container external volume, be effectively increased the volume of container.When vehicle exterior width dimensions is When 2540 millimeters, originally interior width is only 2344 millimeters, after using closing component structure of the present utility model, outside compartment inwall Moving, interior width can reach 2430 millimeters, thus increases inner space, effectively saves space, will not take in case and Size outside case.

The lock fixture employing bending structure of this concealed type lockset, rather than the structure of monoblock, more lightweight than original lockset, Intensity is high.Butterfly folding outward appearance seems butterfly-like, lightweight, and big with car door contact surface, car door connects together with compartment to be had The firm effect strengthened.Concealed type lockset is built-in totally-enclosed, the overall structure suitability and handling more, exquisite attractive in appearance.Normally Car door opening angle 90 degree, butterfly folding of the present utility model can open 180 degree, saves space and is easy to handling goods.

Simply detailed description of the invention of the present utility model described in description above, this illustration is not new to this practicality The flesh and blood of type is construed as limiting, therefore every corresponding amendment being likely utilized and equivalent, belong to this practicality new The apllied the scope of the claims of type.
